Overview
This page is created to investigate Aurora serverless performance by comparing DB xlarge, 8xlarge and Aurora serverless instance types under load running Data Import (DI) with Check-in Check-out (CICO) running as background.
Summary
- The environment can handle the load with all compared DB instance types.
- No significant changes were observed comparing response times for CICO between two instance types db.r6g.xlarge and serverless.
- In Aurora serverless DI duration better for larger DI files.
- Serverless v2 (32 - 128 ACUs) DB instance type configuration performs much better than (0.5 - 128 ACUs) due to increased capacity and its performance closer to 8xlarge. But to cut costs it's better to use (0.5 - 128 ACUs) for DB reader instance role.
- Aurora serverless RDS CPU didn't exceed 25% for any file size. Execution time or test duration has tendency to decreasing for bigger file size because of bigger ACUs.
- To check hypothesis that Aurora serverless configuration changes for Deployments and tasks parameter from 2 to 4 in mod-inventory, mod-inventory-storage, mod-circulation, mod-circulation-storage can lead to test duration decreasing additional DI without CICO were carried out. After check no dependencies are found for that amount of tests. It's considered that 5 or more DI operations needed to get relevant data.
Results
The table includes test results from running on different database instance types Here we observe that RDS CPU utilization for db.r6g.xlarge has maximum values and test duration grows proportional to file size.
But after database was switched to Aurora serverless RDS CPU didn't exceed 25% for any file size. Execution time or test duration has tendency to decreasing for bigger file size because of bigger ACUs.

Running tests for CICO - PERF-593Getting issue details... STATUS I could observe that xlarge used more DB connections than any of DB instance types. The results mentioned in summary table show better response times over time for runs with 20 users. And no significant changes between different DB instance types. High latency was observed for all tests.

For Aurora serverless it was observed response time growth instantly after DI start with smooth decreasing while executing (PTF - Create 2 job profile).
For xlarge DB instance type CPU utilization during CICO stayed stable on level of 15% and after DI with 10k file rapidly go to 93% and stay on this level during all process of DI.
